Apple updated OpenCL Nbody Simulation (= Galaxies) source code a few days (FEB 2014) ago.
I compiled it and uploaded it (DL link at the end of the posting).
Much code changes compared to old galaxies OpenCL bench, so the results arent compareable with old Galaxies anymore.
Now it shows an relative PERFORMANCE Rating value (against an slow single core cpu) - old galaxies showed gigaflops.
Usage, very easy: OpenCL Nbody Simulation starts up in CPU Mode, you can switch by key s to cpu multicore / GPU Mode and back to cpu.
If you have more than one GPU OpenCL device installed, you can try to switch with key g between them. (UNTESTED!)
ESC switches between window / fullscreen mode (fullscreen takes more opengl power = less OpenCL speed)
You can quit the test by using the Menue.
